Abstract
In this work we report an experimental demonstration of broadband wavelength self-tuning in Rb
Nd(MoO
)
laser crystal (RNM) together with a theoretical treatment of the system based on its birefringence properties. The experimental self-frequency tuning of the laser emission along the free spectral range of the RNM crystal (1060-1070 nm) was obtained by rotating the birefringent gain plate in its own plane. To investigate the tuning characteristics of the spectral filter, we have used the Jones-vector formalism. The calculated wavelength-selective tuning matches very precisely the experimental observations.
